The Grammy-winning singer-songwriter will headline a free outdoor concert on Dec. 16 at People's Square in Yangon, at the base of Shwedagon Pagoda.

Mraz is believed to be the first international artist to perform an open-air concert in the country. The show includes local acts and is hosted by MTV EXIT, the music channel's initiative to raise awareness about human trafficking and exploitation.

Mraz hosted a similar concert in the Philippines last year. He says he's going to Yangon "with an enormous amount of gratitude and respect, and I hope we can actually make a difference."

The show will be broadcast on Myanmar national TV and will air on MTV's international network in 2013.
